Võimalik, et seda nüanssi on juba korduvalt jahutud, kui on, siis palun kustutada 
Kas saatan on peidus pisiasjas:
üldjuhul on CD moonutused üliväikesed ja seda ka kõigis tootepassides rõhutatakse. Samas kõlavad CD mängijad erinevalt. Kas võib olla põhjus, et erinevate CD mängijate erinevus tekib üldfoonil vaiksete helide/pillide/häälte moonutustest?
Seda numbrit enamus tootjaid ei maini. Kas puudub neil vajalik mõõtetehnika või meelega vaikivad maha?
Siin nt üks 1989 a CD mängijate võrdlus, kus see number tabelis ilusti kirjas:

Ja-veel: küsimus ja vastus, miks "vana" (2 DAC 4X oversampling) CD mängija on teistmoodi heliga kui “uus”:
How much does the oversampling rate influence the sound of a CD Player?
Q: I have 2 different changers that were built by different companies. I won't say here what the manufacturers but both are from fairly well respected companies and both retailed for over $300 new.
Player #1 was built in 1989 and has 4x oversampling, player @#2 was built in 1998 and has 8x oversampling.
I've been comparing them by playing the same tracks from several different disks and artists.
Now to my ears, the older one with 4x oversamping seems to have a smoother sound. The newer one with 8x seems a bit harsh to my ears. Like there's a bump in the upper midrange.
Some songs also seem to display a slight sibilance in areas where the older one doesn't.
Would that be from the difference in oversampling?
I bought the newer one expecting that it would maybe sound a little better, maybe for some music it would, but from what I've heard so far...not the case.
A: The type of D/A converter has an even greater effect on sound quality than the oversampling rate does. The industry started adopting "one-bit" or "delta-sigma" converters in the early 1990s. These converters need to oversample at a much higher rate than multi-bit converters to provide the same resolution. A true 1-bit converter would have to sample at 65,536x to match the treble performance of a 16-bit converter running at 1x.
I would guess that your 1998 player uses a delta-sigma converter, possibly a Philips Bitstream chip that combines a 5-bit DAC with an oversampling filter or a similar Panasonic MASH chip that uses a 4-bit DAC. At an 8x word clock rate, neither one of these can match a well-designed 16-bit converter running at 4x for treble quality.
